Charming Americans and alarming professionals

Sebastian Vettel was busy helping the Americans with their grasp of Formula 1 last week, while Tony Dodgins was appreciating the mentality of established pros who flirt with the romance, challenge and dangers of the Le Mans 24 Hours

Sebastian Vettel was doing his PR bit for F1 in the US last week; straight after Montreal he flew to the planned New Jersey venue, drove the route in an Infiniti and then headed off to appear on the Late Show with David Letterman.

Letterman, of course, is a race fan and team owner and I wouldn't presume to suggest how he should host a chat show, but it did seem a little odd to have the world champion discussing the ins and outs of DRS activation zones for a US audience!
